Answer 1

$\frac{15}{4} + \frac{16}{3} = \frac{45+64}{12} = \frac{109}{12} = 9 \frac{1}{12}$
$\frac{1}{3} + \frac{4}{7} = \frac{7+12}{21} = \frac{19}{21}$
$\frac{2}{4} + \frac{1}{8} = \frac{1}{2} + \frac{1}{8} = \frac{4+1}{8} = \frac{5}{8}$
$\frac{4}{8} + \frac{1}{2} = \frac{1}{2} + \frac{1}{2} = \frac{2}{2} =1$
$\frac{6}{16} + \frac{6}{40} = \frac{3}{8} + \frac{3}{20} = \frac{15+6}{40} = \frac{21}{40}$
